Documents signed with the Visma Sign Forms service are legally binding, as are any other documents signed through the Visma Sign service. Signers are authenticated by means of strong electronic authentication, and all signing events are carried out using reliable signing methods. 

The electronic signatures are based on the Act on strong electronic authentication and electronic signatures (Act 533 of 2016, available only in Finnish),  and this in turn is based on the eIDAS EU regulation.
